The Effect of Planting Date and Seed Intercropping Ratio on Yield and Yield Components of Maize Intercropped with Soybean (original) (raw)

In order to investigate the effect of planting date and seed mixing ratio on the yield and yield components of maize and soybean, a split plot experiment in as randomized complete block design with three replications was carried out in Ahvaz in 2013. The treatments included three planting dates (D1 = July12, D2 = July 22, and D3 = August 1) as the main factor and the mixing ratio of maize and soybean at five levels (P1 = maize monoculture, P2 = Soybean monoculture, P3 = 50% maize intercropped with 50% soybean, P4 = 75% maize intercropped with 25% soybean, P5 = 25% maize intercropped with 75% soybean) as the sub factor. The results showed that the intercropping ratio only had a significant effect on the number of rows per year in Maize and the highest number of rows per year by 13.5333 belonged to 100% maize monoculture and the lowest number by 12.488 belonged to 75% maize intercropped with 25% soybean. The effect of planting date on the yield and yield components of maize was signif...
